GEORGE MICHAL I-IILGER, OF CHICAGO, ILLINOIS..

VAPOR-GONDENSER.

To all whom it may concern:

Be it known that I, GEORGE M. HILGER, a citizen of the United States,residing at Chicago, county of Cook, State of Illinois, have invented acertain new and useful Vapor- Condenser, of which the following is afull description.

Among the principal objects of the present invention are z-to provide astructural, unit which may be multiplied to increase the condensingcapacity of'the apparatus: to provide a structure wherein the mountingof the operative parts is simplilied: to provide a structure wherein thejoints and possible leakage are minimized: to provide a structurewherein is avoided the possibility of carrying over liquids by theiii-rushing gases: to provide means for trapping and eliminating foreigngases and atmospheric air from the apparatus: to provide an apparatuswherein the condensing capacity may be varied without proportionatelyincreasinO the power circulation.

ln the drawings Figure l is a side elevation of a condenser constructedin accordance with the invention. Fig. 2 is a vertical section of asegment of the condenser constructed in accordance with this invention.

The present invention is shown in the drawings as applied to theconstruction of an ammonia condenser.

The invention is applicable to condensers for steam radiators, for waterheaters, and generally for any system wherein it is desired to extractthe heat by radiation from a gaseous or vaporous substance and therebycondense the said gas or vapor to a liquid and conduct the same from theapparatus by a separate duct.

The gases are introduced through the pipe wlto the head -9-. In theconstruction shown the upper end of the head is closed by the gland -3-which is seated in a suitable recess carrying any well known gasket, Thegland -3- is bolted ho-me as shown in the drawing. Directly beneath thehead 2*- is a column formed by the manifolds M-4-5-6- and -7-. Alljoints in this column between the manifolds, and between the head *2*-and the manifolds, are formed by forming flanges in the one end and agroove in the other end wherein may be inserted a gasket. All gaskets insaid joints are compressed by means of bolts Specification of LettersPatent.

the liquid return pipe -13-- The manifolds 4-5-6- and -7, in the presentinstance, are similar in construction. If desired, however, manifolds oflarger radiating capacity could be substituted for any one or more ofthese said manifolds, without changing the operation of the apparatus.By this means the condensing capacity of an apparatus so constructed maybe nicely adjusted. As each manifold carries a number of radiating pipesextended from the same pressure chamber, the circulating pressure formoving the gases is not increased by thus increasing the condensingcapacity.

Each manifold consists in a tubular three chambered metal casting. Theopen ended chambers -l4- and l5- and the totally inclosed chamber, 16-extend longitudinally and are formed by the partitions -17-- and -l8*,cast with body of the manifold. The manifold shown in the present drawings is provided with six condensing extensions composed of the externalpipes 19 and the internal pipes 20. These extensions are in eachinstance similar. To receive the pipe -19-, the manifold is providedwith the perforations -21-- The perforations 2lq are suitably reamed toform a seat for the end of the pipe -l9-. The joint is gas sealed byforming a groove surrounding the perforation n-Qlto receive the gland22- which is constructed in the usual manner, having a flange adapted toseat in the said groove. The glands 22- are held in position by bolts-23-, as shown in Fig. 1 of drawings.

The pipe -19- in being mounted is inserted over the pipe -20-. The pipes-20- are preliminarily secured in the partitions 17- and -18 inperforations concentric with the perforations 2l- The perforation in thepartitions -l7- and m18- are tapped to receive the screw threaded endsof the pipe 20- The pipe -20- is extended through the partitions -17-and -l8- to near the opposite wall ofl the chambers *14k-'and -l6- toproduce the overhanging ends 24E- within When the manifolds are coupledin column,

said chambers. The outer or far end of the pipe -20- is supported bysuitable rel eeptacles -25- in the outer or farther ends I of the pipe-19-. The pipe -19- is supported by the lstandards 2G-26, which are ofthe usual construction. These standards are mounted in the drip pan 27-,in which are also mounted the standards -28- to support the columns ofmanifolds. Y Y n Vhile I have herein described the manifolds as havingthe three chambers -14-15- and +16-, it is evident that I could dividethe manifold in equal parts to produce a manifold having the chambers14C- and V--l6-, or -15- and 1G- each by dividing the manifold, shown inthe drawings, at the longitudinal center thereof. Insuch case eachsection or manifold, would carry the three extension pipes instead of,as in the present instance, the six extension pipes.

l At the bottom of each chamber -1t-15- or -16-, is introduced an outletnipple -29-, which'is connected to a pipe connection -30-, in which ismounted a valve -31-. The connections -30- are joined by the sections32- which form the return pipe for the condensed liquids. Extending fromthe uppermost connection -30-, is a short pipe section controlled by thevalve -33- whichcont-rols the entrance to the separating chamber '-3t,where in the operation of this apparatus, foreign gases and atmosphericair are trapped. The said gases when trapped are expelled from thechamber -34- through the pet cock 35 with which the said chamber isprovided.

An apparatus thus constructed operates as follows The gases or vapors tobe condensed are admitted through the pipe 2land head -2- into thechamber -llof the manifold. From the chamber +14- the gases are forcedthrough the pipes 20- out to the far end of the same where they areintroduced into the pipe -l9-- The pipe -19- is closed at the far endand opens only into the upper end of the chamber -16- of the manifold.The chamber --16- has two extensions as shown in drawings, whereby itreceives the gases from the pipe V 1Q-- in the upper half of saidchamber and the lower half of the chamber is in open communication withthe pipes -20-. In the lower half of the manifold the action of thepipes *20- and --19- is the same as described above as transpiring inthe upper half of the manifold. As the manifolds are joined, eachchamber -15- is superimposed upon and is in open communication with thechamber -14- in the unit next below, whereby the combined chambers 14and -15- form a continuous chamber similar in section to the chamber-16-.

the action of the apparatus is to force the gases outward from onechamber through a series of three or more extension pipes -20- to bereturned to a different chamber by the pipes -19-. From the said secondchamber the gas is conveyed to and again forced out through a pluralityof pipes 20- to be again returned to a different and successive chamberby the pipes -l9-. This action is repeated in each manifold, or unit,continuously transferring the gases from one to another chamber througha long outward extended and returned radiating member. These radiatorsmay be air cooled or water cooled, as desired and as necessitated by thematerial being treated. Somewhere in the passage from the uppermost tothe lowermost of the manifolds the vapors will be condensed, and in thecondensed form be returned to the chamber 16- or -15- as liquid. Theliquid will then iow down the wall of the chamber through which thepipes -l9- are inserted, and continue on the walls of the partitions -l7and -lS- and around the extended ends 24kof the pipes --2 Ultimately theliquid iows to the end of the chamber 16M or -14-- and is conductedthence by way of the nipples -29- through the valves -30- to the pipe-32 and thence to the uppermost valve 30- and out on the return pipe tothe storage tanks provided for the liquid. It will be observed that bythe extension of the ends 424tof the pipes QG-3 the liquid is notcarried into the pipes 20- by the lnrush of the outward passing gases.In the event foreign gases are contained in the gases being condensed,these will not become liquid but will pass out of the manifolds throughthe nipples -29- and be thence transferred through the pipes -32- to thechamber -3t-- In normal operation the valve S3- is open, and the cock-35- is closed. When the presence of foreign gases in the chamber -34-is suspected or indicated, the valve -33- is closed and the cock -35- isopened to permit the escape of the foreign gases and atmospheric aircontained within the chamber -3l*. The chamber -84rmay be provided withany of the well known mechanical appliances for collecting the said airand gases by creating therein a rareied atmosphere. The gases havingbeen withdrawn from the chamber S4- the cock 35- is then closed and thevalve 33- opened, when the accumulation of the foreign gases againproceeds as prior to the interruption. Any uncondensed gases which maypass to the bottom of the pile of manifolds may be returned to thecirculating system through the pipes -10- to be again returned throughthe condenser until condensed.

A condensercomprising a plurality of manifolds having two chambers formed by ahinner partition integrally formed therewith to produce a receiving and adistributing chamber', said chambers being so formed that the receivingchamber of the one manifold registers with the distributing' chamber ofthe manifold immediately below, a series of radiator pipes extended fromthe distributing chamber through the receiving chamber in each manifold,a series of return pipes opening into and delivering into the saidreceiving chamber in said manifold, and a return liquid system adaptedto extract the liquid from the lower end of said distributing chambersin each manifold.
